SPECIFICATION formingpart of Letters Patent-NO. '7 00,531 dated May 20, 1902.

Application filed April 26, 1901.

To all whorm it may concern.- v 1 Be it known that I, JOHN C. MILLER, a citi; zen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented newan'd useful Improvements in Cooling and Aerating Devices, of which the following is a specification. f I a This invention relates to cooling and aerating devices for use in cooli ng,[aerating, and deodorizing milk, andhas for 'its object the production of a' simple, convenient, and effective devicef'of this character embodying certain improvements in construction, which will be hereinafter more fully described, and particularly defiped in the appended claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective View of a milk-cooler and aerator embodying my invention. Fig. 2 is a central vertical sectionlthereof. Fig. 3 is atop plan view of thecorrugated cone. FigA i's a side elevation of the same. r.

Referring now more particularly to the drawings, the numeral 1 represents a cooling vessel which is in form-of a truncated cone and has a fixed inclined top 2 and an annular bottom trough 3. On the interior of this vessel is arranged a frusto-conical spirallystepped partition 4, consisting of a continuous spirally-wound metallic strip, said partition being closed at its upper end by an inclined" top 5 and having exterior spirally-arranged horizontal ribs 6, forming, with the vessel 1 and said partition 4, a spiral or serpentine passage 7,'extending from bott0m;to-top of the vessel 1. The inclinedtops 2 and 5 of the vessel andpartition t are spaced apart to form a passage 8, which is in communication with said passage 7, and a tube 9 connects said passage 8 with the'interior of the vessel 1.

10 represents a discharge-tube, through which the cooled and aerated milk discharges from the trough 3 into cans or other suitable storage-receptacles, and 11 is an inletetube for conducting the coeling-waterfrom asui'table" source of supply under pressureto the lower end of the serpentine'passage 7.

Secured to the central portion of the inclined top 2 of the vessel 1 is a corrugated cone 12, having its apex directed upward and projecting through a discharge-aperture 13 in the bottom of a superimposed milk-receiving Serial 1% 57,52 (No oan.)

pan or reservoir'ltt, This pan or reservoir 14 is'adjustably mounted on supports having turnbuckles 15, wherebythe pan may be adj ustedjup and down to regulate the flow of the milk-through" the corrugations of the cone.

The corrugations in the cone 12 are proward flowof themilk from the pan 14:, but also to break up'the solid body of milk into a plurality of divided streams and to cause the milk to spread equably in a thin sheet over the entire surface of the inclined top 2, so as to secure rapid and effective cooling. f

-,In using my'improved cooler and aerator Qthe vessel 1 is kept cool by a constant supply of cold water, which enters the passage 7 at the bottom through the tube 11 and is forced up under pressure through the various steps spirally until it reaches the top, when it enters the passage Sand then discharges through the tube'9 into a receptacle of any preferred ikindlocated within or below the vessel 1.

the vessel '1, which are kept cold by the circulating water, the milk is relieved of its animal heat and aerated, and when it reaches the trough 3 is thoroughly cooled and deodorized. The feed of th'e'milk undergoing the cooling process from the pan or reservoir 14c is controlled by adjusting said pan up or down, which regulates the amount passing through the corrugations of the cone -12. V t

The invention is simple, cheap,anddurable in construction and isadaptedto perform its work in an effective manner. I l 1 Having thus fully described my invention,

what I claim, and desire to secure by Letters "Patent, is

A milk-cooler comprising a frusto-conical wall,an inverted dished top forming a slightlyvided not'pnly, to form passages for the downinclined and comparatively broad supporting mo and milk-distributing surface, a frusto-conical spirally-stepped partition upon the interior of said vessel and forming a serpentine passage for the circulation of a cooling liquid,

into said orifice, supports between the reservoir and top of the cooling vessel, and turnbuckles carried by said supports for adj usting the reservoir up and down to vary the position of the cone Within said orifice, substantially in the manner set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN C. MILLER.
